The Redding .375 H&H Magnum Full Length 2-Die Set (Series A) is a precision reloading tool designed to restore fired .375 Holland & Holland Magnum bottleneck belted brass cases to factory SAAMI minimum dimensions.

Who is the Redding 375 H&H Holland & Holland Die Set Ser A for?

  • Dangerous Game Handloaders — Assembles heavy-recoiling hunting ammunition for water buffalo and scrub bulls using an integrated roll crimp ring on this 375 H&H reload die set to prevent 0.375-inch projectiles from shifting under recoil, mounting securely to any press using industry-standard 7/8"-14 threading.
  • Northern Australian Safari Hunters — Restores fired brass to factory SAAMI dimensions to ensure flawless feeding in custom and factory bolt-action rifles, requiring standard 7/8"-14 threaded presses paired with a dedicated #6 shellholder to process full-length cases.

Less suitable for: Handloaders processing non-belted large-bore cartridges such as the .375 Ruger or .375 Remington Ultra Mag, which require dedicated non-belted magnum resizing dies, or reloaders seeking neck-only brass resizing for single-rifle brass longevity, who require a dedicated neck-sizing or deluxe 3-die set instead.
